ummm, not sure i understand your English.  Github is the depository and most coins put theirs on there.  For a released coin, like this one, you do not need to touch the github source.  you have the wallet and that is enough for you.  the source allows people like us to look through the code and see red flags.  Anyone can release a coin and release a wallet.  I can code a coin and wallet and make them very attractive, even profitable.  However, I can include in that code access to many things.  I can assume that you have the Bitcoin core and wallet installed if you installed my new coin.  i can send commands to bitcoind to send BTC to my address.  I could even possibly pull off copying and sending the wallet.dat file from your bitcoin wallet to my server.  I can search and send any and all files called wallet.dat to my server and inculde the directory info they came from.  Depending on some things, that gives me control of those wallets and the funds.  I can control your copy/paste clipboard and everytime you copy and paste a BTC address, the clipboard changes it to mine, meaning that everytime you send BTC to someone, you send it to me.  

that, combined with things like pre-mining, reward structure, staking interest and time, difficulty progression, these are things we NEED to see and know before dealing with a coin.  for you, look at the forum before downloading and installing a wallet and stick to premade/compiled wallets to start.  you will learn as time goes by and feel free to look through the github source and read the code, many of them are commented and you will be amazed how complex the simple system of crypto can be
